NSW DMR, Discovery 2000, Cargelligo/Narrandera, AREA H, 1995 (P738), elevation line data

The Digital Elevation Model represents ground surface topography between points of known elevation. The elevation data was calculated using the altimeters and Global Positioning System (GPS) sensor used for the benefit of airborne magnetic and radiometric data on the same survey. The elevation is the height relative to the Australian Height Datum GDA94 (AUSGEOID09). The processed elevation data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose. These line dataset from the NSW DMR, Discovery 2000, Cargelligo/Narrandera, AREA H, 1995 survey were acquired in 1995 by the NSW Government, and consisted of 123700 line-kilometres of data at 250m line spacing and 60m terrain clearance.

数字高程模型（Digital Elevation Model）用于表征已知高程点之间的地表地形。本次高程数据通过为同一调查中的航空磁测与放射性测量作业配套部署的高度计与全球定位系统（GPS）传感器计算所得。本次采用的高程为相对于澳大利亚大地基准GDA94（AUSGEOID09）的海拔高度。经处理后的高程数据将由澳大利亚地球科学局（Geoscience Australia，GA）的地球物理学家开展质量核查，以确保该局发布的最终数据符合使用需求。本次测线数据集源自新南威尔士州矿产资源局（NSW DMR）"Discovery 2000"项目下卡格里戈/纳兰德拉区域H的1995年航空测量作业，由新南威尔士州政府于1995年采集完成，总测线长度达123700千米，测线间距为250米，作业地形离地飞行高度为60米。
